For AVX-512 we can do the following equivalents

The Int_VCVTSD2SSrr can use VCVTSD2SSZrr. This for some reason doesn't use _Int but does have VR128X register type.
The Int_VCVTSS2SDrr can use VCVTSS2SDZrr. Again it uses VR128X type.
The Int_VCVTSI2SS64rr patterns can use VCVTSI642SSZrr_Int
The Int_VCVTSI2SSrr patterns can use VCVTSI2SSZrr_Int
The Int_VCVTSI2SD64rr patterns can use VCVTSI642SDZrr_Int
The Int_VCVTSI2SDrr patterns can use VCVTSI2SDZrr_Int.
